[Wien] x spaghetti problem for spin-orbit calculation on rhombohedral structure

[iaki island]

Dear Wien Users,

- I am running wien version 10.1 on a machine of type Intel(R) Xeon(R) CPU
 with
operating system GNU/Linux, fortran compiler 77.

- The purpose of my calculations is to get quantity Spaghetti.

- I am running this case (TlBiTe2.struct) using this input (below) and
these commands (x spaghetti).

The "x spaghetti" calculation has a problem along specific parts of the
Brillouin zone in that it is not able to calculate them. When I try to
calculate the band structure along the reciprocal co-ordinates:-

 0.0 0.0 0.0 (Gamma point)
 0.5 0.0 0.0
 0.5 0.0 0.5
 0.0 0.0 0.0 (back to Gamma)

I get the following output from "x spaghetti"  :
-----------------------------------------------------------------
number of k-points read in case.vector=         201
 here          67 C2h
SPAGH END
0.222u 0.149s 0:00.37 97.2% 0+0k 0+0io 0pf+0w
-----------------------------------------------------------------

After this, the spaghetti cannot be calculated.
So there appears to be a problem a k point 67, belonging to the irreducible
representation C2h.
Any ideas why I am having this problem? Any ideas how to solve this? Can I
provide more information? I have searched the archives of this forum with
vanishing success.

Many thanks

- Yes, I have browsed the archives AND READ THE USERS GUIDE and the
FAQ pages Peter provides, but I couldn't solve my problem that way.
